Question

I am trying to update a row in MySQL database from within ASP.NET using ASP.NET.

    MySqlConnection cnx = new MySqlConnection(con);
    MySqlDataAdapter adapter = new MySqlDataAdapter();

    DataTable dt = new DataTable();

    dt.Columns.Add("id", typeof(Int32) );
    dt.Columns.Add("config", typeof(string) );
    dt.TableName = "sharding_conf";
    DataRow dr =  dt.NewRow();
    dr["id"] = 1;
    dr["config"] = json;
    int ok = adapter.Update(dt);

    lblTest.Text = ok.ToString();

    cnx.Dispose();
    adapter.Dispose();

However the row is not getting updated, any suggestions?
